Kristen Wiig may be about to strike comedy gold once again!

The Bridesmaids star talked to ET ahead of the premiere of Downsizing, her new film with Matt Damon, where she shared that she and writing partner Annie Mumolo -- who earned a Best Original Screenplay Oscar nomination for their unbelievably funny 2011 comedy -- are working together on a new project!

"My writing partner and I have been for a long time writing a script, and now we're [in] final rewrite stage, which is very exciting," the 44-year-old actress revealed. "It's called Barb and Star go to Vista Del Mar."

Not to judge a movie by its title, but we are already one hundred percent in for this when it comes out.

In the meantime, Wiig is currently promoting Downsizing, a sci-fi dramedy about a couple that shrinks down (quite literally) to retreat from the stresses of modern life, which reunites her with The Martian co-star Damon.

In The Martian, we were on two different planets," she noted of working with Damon, saying that their professional relationship made for "instant friendship."

"We just got along really well and he's super funny," Wiig added.

Downsizing brings a smaller life to the big screens on Dec. 22.
